Why Glass Beats Plastic Every Time
Many cold frames use polycarbonate or cheap plastic panels, but we believe your plants deserve better. Our Grade A toughened safety glass offers:
- Superior light transmission - maximising winter sun exposure
- Better insulation properties than plastic alternatives
- Enhanced durability - won't yellow, crack, or degrade
- Professional appearance that complements any garden
- Easier maintenance - simply wipe clean
The difference in soil temperature insulation compared to plastic alternatives is remarkable, creating a stable environment your plants will love.
Perfect Size for Every Garden
At 2.5ft x 3ft, our cold frame strikes the perfect balance between growing capacity and garden practicality. This size allows you to:
- Fit comfortably in most garden spaces
- Accommodate multiple plant varieties
- Easy access for watering and maintenance
- Manageable lid operation
- Efficient use of your growing area
